The chart shows the number of deaths reported for 108 major cities of the United States by week for the current year, and, for comparison, the median of the number of deaths reported for the corresponding weeks of the 3 previous calendar years. (The median is the central one of the three values arranged in order of magnitude.) If a report is not received from a city in time to be included in the total for the current week, an estimate is made to maintain comparability for graphic presentation.

The figures reported represent the number of death certificates received in the vital statistics offices during the week indicated for deaths occurring in that city. Figures compiled in this way, by week of receipt, usually approximate closely the number of deaths occurring during the week. However, differences are to be expected because of variations in the

interval between death and receipt of the certificate.

While week-to-week changes in the total number of deaths reported for all major cities generally represent a change in mortality conditions, this may not be true for variations in weekly figures for each city. For example, in a city with a weekly average of 50 deaths, the number of deaths occurring in a week may be expected to vary by chance alone from 36 to 64 (d2d, where d represents the average number of deaths per week).

The number of deaths in cities of the same size may also differ because of variations in the age, race, and sex composition of their populations, and because some cities are hospital centers serving the surrounding areas. Changes from year to year in the number of deaths may be due in part to population increases or decreases.

ported as showing Pasteurella multocida.

The only other isolation of Pasteurella multocida associated with human illness in Connecticut by the laboratory of the State Department of Healthin recent years occurred in January 1955. The patient, in this instance, was a 78-year-old woman who gave a history of having been bitten on the arm about a month earlier by her pet cat. The lesion had healed, but about 1 week before admission to a hospital her arm became red, hot, tender, and swollen. The abscess was opened on January 26, 1955, and drained of about 100 cc. of yellow pus. Pasteurella multocida were cultured from this pus. The patient recovered and was discharged from the hospital on January 30, 1955.

(This organism causes pasteurellosis or hemorrhagic septicemia in birds and mammals.)

Typhoid fever

Dr. G. J. Van Heuvelen, South Dakota Department of Health, has supplied epidemiologic information on 8 cases of typhoid fever reported in Corson County during October 1955. The cases were among Indians who live in 66 small substandard and overcrowded houses. Modern sanitary facilities were not available, and conditions in and around the area were deplorable. Water was from wells, one of which was an approved source but pumping facilities and distance prevented it from being ideal for the whole community. Laboratory work was done in North Dakota, and the report has not yet been received.

Gastro-enteritis

The Oregon State Board of Health has reported an outbreak of gastro-enteritis involving 5 of 6 persons at a family gathering. They became ill from 2 to 4 hours after eating chocolate eclairs which were purchased from a local bakery. No food was available for bacteriological examination. However, an investigation of the bakery indicated improper preparation and cooling of the eclair filling. The finished product was stored at room temperature.
